To evaluate performance of the Minolta JM-103 Jaundice Meter (JM) as a predictor of total serum bilirubin (TSB) in outpatient neonates during the first week postnatal, and to estimate the number of TSB determinations that might be avoided in clinical use.
In neonates evaluated posthospital discharge, JM and TSB results were compared using linear regression and a Bland-Altman plot, and predictive indices were calculated for various JM cutoff values. Utilizing the 2004 American Academy of Pediatrics (AAP) guidelines, the ability of JM to predict risk zone status was determined.
Overall correlation between JM and TSB was 0.77 (p<0.001; n=121). When TSB was >17 mg/dl, a cutoff value for JM of 13 mg/dl had a sensitivity of 1.0, and 50% of TSB determinations would be avoided.
JM may facilitate outpatient management of hyperbilirubinemia by reducing the number of TSB determinations required; however, it does not provide a reliable substitute for laboratory measurement of TSB.
评估美能达JM - 103黄疸仪（JM）作为预测出生后第一周门诊新生儿总血清胆红素（TSB）水平的性能，并估计在临床应用中可避免的TSB测定次数。
在出院后接受评估的新生儿中，使用线性回归和Bland - Altman图比较JM和TSB结果，并计算不同JM临界值的预测指标。根据2004年美国儿科学会（AAP）指南，确定JM预测风险区域状态的能力。
JM与TSB的总体相关性为0.77（p<0.001；n = 121）。当TSB>17mg/dl时，JM的临界值为13mg/dl，灵敏度为1.0，可避免50%的TSB测定。
JM可通过减少所需的TSB测定次数来促进门诊高胆红素血症的管理；然而，它不能可靠地替代TSB的实验室测量。
